• Performing a fuzzy search may retrieve terms with similar spellings: doc hieu manh - manh ((((trung cua) OR (trung cap))) or (trung tuan)) khong huong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu manh - manh ((((trung cua) OR (trung cap))) OR (trung tuan)) khong huong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu manh - manh ((((trung cua) OR (trung cap))) or (trung tuan)) khong huong dan toan ban".
• Adding a wildcard symbol may retrieve word variants: doc hieu manh - manh ((((trung cua) OR (trung cap))) or (trung tuan)) khong huong dan toan ban*.
